Answer number 4 and explain please. Thank You!

Alt Alt Fn Ctri 76 QUESTIONS/CALCULATIONSs ). Which metal had the greatest heat capacity? 2 Which metal had the greatest specific heat capacity? Aluminum 3. Is the metal with the, greatest heat capacity the same metal that has the greatest specifice heat capaciy? e a. If so, would any sample of this metal always have a greater heat capacity than any other sample of another metal? Explain why (Hint: Think about the relationship between hçat capacity and specific heat capacity) rial, an on arou kent capac (enu/other 'hard does depend on the amoun substhance, so, No thy metal ith the greatest capod t have b. If not, explain how one sample of a metal can have a greater heat capacity than another metal with a greater specific heat capacity (Hint: Think about the relationship between heat capacity and specific heat capacity). . Assume you repeated this procedure again and the only change in your procedure was that 50.0 g of cthanol (accepted specific heat value of 2.44 Jg C) was used instead of 50.0 g of water (accepted specific heat value of 4 18 J/g C) in the Styrofoam cup. Would the change in temperature of the ethanol (new procedure) be more, less, or the same as the change in lassume the same piece of metal used in each experiment with the same initial tempera- ture)? Explain why Proof It

Explanation / Answer

Heat released by metal = heat abosorbed by liquid

q(metal) = mass*specific heat*deltaT

Delta(T) =q(metal)/(mass *specific heat)

Delta (T) is change in temperature of liquid.

q(metal) and mass of liquid are constant in both the experiments, only specific heat is different.

If the specific heat of liquid is more then it's temperature change is less, if specific heat of liquid is less then it's temperature change is more.

Ethanol has less specific heat (2.44) than water (4.18), so change in temperature of ethanol is more when compare with change in temperature of water.
